To a/ZZ whom. it may concern,.-

Be it known that I, JAMES H. NORTHROP, a citizen of the United States,and a resident of Tustin, county of Orange, State of Califor- ThreadingLoom-Shuttles, of which the following description, in connection withthe accompanying drawings, is aspecication, like letters on the drawingsrepresenting like This invention has for its object the iinprovement inloom-shuttles whereby pinching of the running thread when the shuttle isin use and consequent severance of the The usual loom-shuttle isprovided with an external longitudinal groove or recess extended alongone side of the shuttle-body from the thread-delivery eye to receive thepinched between the side of the shuttle-body and the wall of theshuttle-box. So long as the thread lies properly in such groove there isno opportunity for pinching; but the will often tend to lower it, sothat it will be caught between the front wall of the shuttlebox and theside of the shuttle, above or below the groove. In my present inventionI delivery eye located adjacent the bottom of the shuttle, and I havealso shown the threadgroove located on the side of the shuttle-bodyadjacent the bottom thereof, so that if the drops onto the bottom of theshuttle-box.

Figure lis a top or plan view of a Wellknown form of loom-shuttle havingmy invention applied thereto. Fig. 2 is a side elevaand thethread-groove adjacent the bottom of the shuttle-body. Fig. 3 is atransverse sectional view on the line o: fr, Fig. 1, looking to theleft, to show more clearly the thread- I have herein shown my inventionas applied to an automatic self-threading shuttle, substantially such asshown and described in United States Patent No. 574,864, granted fillingcarrier or bobbin B, having the rings a at its base, the holding-jaws C,and the aumatic self-threading device D may be and are substantially asin the patent referred to, the

threading device being provided with a longitudin al thread-entrance d',(see Fig. 1,) having at one side a horn d2, a space oll being leftbeneath the outer end of the horn and the top of the shuttle-body toconduct the thread through a downwardly-inclined slot d to thethread-delivery eye e. As shown in Fig. 2, the thread-delivery eye islocated adjacent the bottom of the shuttle-body, sothat the threadinstead of being delivered from the side of the shuttle substantiallymidway between the top and bottom thereof is delivered at or near thebottom.

A longitudinal thread-groove h (see Fig. 2) is formed in the outer faceof one of the side walls of the shuttle, leading from the delivery-eye etoward the opposite end of the shuttle, the groove being locatedadjacent the bottom of the shuttle. By reference to Fig. 3 it will beseen that t-he groove is formed by the overhanging shoulder hX, so thatif the thread drops it will drop onto the bottom of the shuttle-box andcannot be pinched between the front plate thereof and the side face i ofthe shuttle.

By the longitudinal axis of the shuttle I mean a line extendedlongitudinally through the shuttle from one to the other point thereof.

I have herein shown my invention as applied to a shuttle provided withan automatic threading device; but my invention is not restricted tosuch application, as it may be used in connection with other types ofloomshuttles.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A loom-shuttle rectangularin cross-section and having athread-delivery eye in-its side, and a longitudinal threadgroove on the'shuttle side at the bottom thereof, leading from the eye.

2. A loom-shuttle, rectangular in cross-section and having an automaticself-threading device, and a thread-delivery eye in the side of theshuttle and adjacent the bottom thereof.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JAMES II. NORTI-IROP.
